Formatting and Metadata Criteria

Looking for the Mapping Criteria? The ScoreSaber Mapping Criteria can be found here

Rules

💡

The data on external sources do not have to abide by these rules, but should be kept relevant to the song and artist. You may add additional tags and other information. The metadata rules in this document are for in-game purposes.

Official metadata should be used in all fields, then follow the formatting as explained below. In the case of a contradiction, follow the official metadata. In the case that the official metadata uses unsearchable characters (anything besides A-Z, 0-9) then please refer to Unsearchable characters, translations, and romanization below.

Regular Use Case

In the vast majority of cases, song metadata should follow this format:

levelAuthorName: Mapper
songAuthorName: Artist of the song
songName: Song name
songSubName: All following tags: (Short Ver.), (ft. Hatsune Miku), etc.

If there are multiple tags, then put them alongside each other in the songSubName in any order. Do not add any tags that are not specified in this document or the official metadata. The type(s) of brackets and other typographical marks used in tags, if used, should follow the official metadata if available.

Example:

levelAuthorName: Uninstaller
songAuthorName: Camellia
songName: Bassline Yatteru? w
songSubName: feat. Nanahira (Cranky Remix) (Short Ver.)

Track is a remix or other musical modification of the original

The remix, bootleg, etc. tag must go into songSubName in brackets regardless of official or source metadata.

Example:

songAuthorName: DJ'TEKINA//SOMETHING
songName: Internet Bitch
songSubName: (P*Light Remix)

Track is a cover

The cover artist, followed by “Cover”, must go into songSubName in brackets regardless of official or source metadata.

Example:

songAuthorName: 150p
songName: Kodoku no Kakurenbo
songSubName: (Himeringo Cover)

Track has an official length modification

If the track is an official length modification, the source metadata should be followed.

Example:

songAuthorName: Camellia as "fluX Xroise"
songName: Xronier
songSubName: (”geneXe” Long ver.)

Track has an unofficial length modification

If the track is modified in such a way that it is similar enough to an official version of the track, the source metadata of that version of the track should be used.

If the track is a shortened version of the full version of the track for the purpose of animation openings or endings, then (TV Size) must be added to the songSubName.

Example:

songAuthorName: PENGUIN RESEARCH
songName: HETENA
songSubName: (TV Size)

If the track is simply shortened, then (Short Edit) or (Short Ver.) must be added to the songSubName. If the original track metadata already has a length designation, (Short Edit) or (Short Ver.) must replace the original length designation.

Example:

songAuthorName: VINXIS
songName: Sidetracked Day
songSubName: (Short Edit)

If the track is extended in some way, (Extended Edit) or (Extended Ver.) must be added to the songSubName. If the original track metadata already has a length designation, (Extended Edit) or (Extended Ver.) must replace the original length designation.

Example:

songAuthorName: ExileLord
songName: Soulless 5
songSubName: (Extended Edit)

Track is a mashup

Use the information provided by the artist.

Examples:

songAuthorName: gmtn. vs. kozato (fw. LUZE) & gmtn. (witch’s slave)
songName: squartatrice vs disperagioia

songAuthorName: Kove x Perfume
songName: Stellar x Polyrhythm
songSubName: (TANUKI Mashup)

Track has vocals from a Vocaloid

Vocaloids are rarely the sole artist for a song. The producer or artist must be placed in the songAuthorName, and the Vocaloid featured must be added to the songSubName.

Example:

songAuthorName: Rasen Hikou
songName: Omoi
songSubName: [ft. Hatsune Miku]

Track has multiple artists

Comma separation

Source metadata must be used, and the artist names should be separated by a whitespace.

Example:

songAuthorName: TEA, ginkiha
songName: Luvin’Epoch

vs. (Versus)

vs., VS, and Versus are commonly used to indicate a collaboration between two artists. The source metadata should be followed as is.

Example:

songAuthorName: C-Show vs. DJ Genki
songName: BLACK LABEL

With

With is commonly used to indicate a collaboration between two artists. The source metadata should be followed as is.

Example:

songAuthorName: Minazuki Airi with Atsushi
songName: Daisuki, Evolution

And (or &)

And (or &) is commonly used to indicate a collaboration between the two artists. The source metadata should be followed as is. Do not replace an ampersand with “and” or vice versa.

Example:

songAuthorName: Draw The Emotional & Foreground Eclipse
songName: Sad Spring

Feat (or ft.)

Featuring (aka. feat. / ft.) is commonly used to indicate a collaboration between the two artists. This can appear in both the artist name and the title name. Always put the feat/ft. Sections inside songSubName.

Example:

songAuthorName: The Black Eyed Peas
songName: DOPENESS
songSubName: (feat. CL)

CV (Character Voice)

Character Voice (CV) is typically used when the vocalist is singing under the alias of a character from a show. This is rarely consistent so is enforced as such, in spite of official metadata.

The correct way to format CV designations is to use the romanised name of the character within brackets, followed by the romanised name of the vocalist with CV: as a prefix, in brackets.

Examples:

songAuthorName: Emilia (CV: Rie Takahashi)
songName: Stay Alive

songAuthorName: Tanya Degurechaff (CV: Yuki Aoi)
songName: Los! Los! Los!

Track has 3 or more artists

When 3 or more artists are involved with a track, Various Artists should be used instead.

Example:

songAuthorName: Various Artists
songName: Songs Compilation

Map has multiple contributors

When there are two or more contributors, each contributor can be named individually as long as the in-game character limit is not exceeded; in doing so, all contributor names must be present and separated with the correct punctuation.

Should the character limit be exceeded, the levelAuthorName must be replaced with "Various Mappers" or an alternative group name, and all contributors must be credited on the relevant beatmap source pages or listed inside custom DAT file fields.

Alternative group names are allowed for a collaboration of 2 contributors or more. A group name must not exceed the character limit unless the group name is 15 characters or less.

Example:

levelAuthorName: Amanatsu & Kikis  
songAuthorName: Camellia  
songName: finorza  
songSubName: feat.Nanahira  

levelAuthorName: DE125, Skeelie, & Vilawes
songAuthorName: ReeK
songName: Possesed By The Blood Moon

Unsearchable characters, translations, and romanization

Official metadata should be used in all fields, even if it contains unsearchable characters, as long as there is a significant string of searchable characters in each field. In all cases, official translations of metadata, as well as romanization, can both be used at the mapper's discretion. "Significant string" will be defined on a case-by-case basis where searchability of the string is prioritized.

Example of acceptable, searchable metadata:

levelAuthorName: Uninstaller
songAuthorName: KIVΛ
songName: Code:11

Other examples of searchable metadata:

XHRONOXAPSULΞ, t+pazolite, ΩΩPARTS, †:OLPHEUX:†, +ERABY+E CONNEC+10N, AμreoLe ~for Triumph~, \frac{\textup{sig}=\frac{821}{149}}{bpm\approx533}, 嚮導BRING+瞳EYES=死DEATH+齎INVITE

If the official metadata for any field does not contain any searchable characters, then official translations or romanization should be used. We will use "ヒアソビ" by かめりあ as an example here.

Example of official translation:

levelAuthorName: Amanatsu
songAuthorName: Camellia
songName: Play with Fire

Example of romanization:

levelAuthorName: Amanatsu
songAuthorName: Camellia
songName: Hiasobi

All cases where a map would break any metadata criteria, but cannot be changed in a way that would adhere to the metadata criteria for any reason, will be handled on a case-by-case basis.

Example:

levelAuthorName: Skeelie
songAuthorName: x0o0x_
songName: / / // / /
